Another method is to import the material into the superimposed track and drag the four corners of the image in the preview window, so that the subtitles can be shared outside the window, and there will be no subtitles when playing. This is a good method, but some pictures will be removed on the left and right sides. If there is no lack of adjustment, the image will be deformed and thinned.
No matter what video editing software, subtitles and images are integrated, and it is impossible to remove subtitles in a pure sense, so the above methods can only be used.
